IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent N0.,174,464, dated March 7, 1876; application led November 2, 1875.

To all whom it may concern:

Beit known that I, ARTHUR BARBARIN, a resident of the city of New Orleans and State of Louisiana, have invented a certain new and useful Improvement in Scotch-Tip Gras-Burners 5 and I do hereby declare the following` to be a full. clear, and correct description of the same, reference being had to the annexed drawing, making a part ot' this specification.

Myinvention consists ot' an improvement upon the well-known Scotch-tip gas-burner, by

' the old Scotch-tip gas burner, the upper end of which, being also threaded, is more contracted than its lower threaded end. B is the ordinary socken stem of the same; but, in this improvement, it is longer than usual, and providedwith an open upper end to receive the lava or other tip, and, instead of being open at its lower end, the same is closed, and provided with a couple ot'perforations, c c, a little above the said closed end, facing each other, and communicating directly with the interior of the threaded socket-stem.

To operate this device, as in the case of the old Scotch-tip gas-burner, the socket-threaded stem is screwed into the upper end of the base A. The lava or other tip, c', being placed into the socket-stem, as shown upon the drawing, the lower end of the vbase A is screwed upon the gas-chandelierV or bracket. On gas being turned on, the same is ignited, and, by screwing or unscrewing the socket-stem, the perforations c c are more or less encircled, and, consequently, opened or closed, by the threads of the upper end ot' the base, so that it' a rated tip requires a larger volume ot'` gas to lill its flame than another,`by screwing the socketstem down the perforations c c are made to descend below the lower threads of the upper end of the base A. This, then, admits the holes in a wider portieri of the base, and allows' the gas to enter the stem in a larger quantity, and, as these perforations face each other, the two jets of gas, on entering the holes under pressure, impinge against each other, and, consequently, deaden their pressure very near the point of consumption.

To still further retard the pressure, small pieces of wool or other fibrous or porous material maybe inserted Within the channel of the stem for that purpose.

As will readily be perceived, the object of the check-nut d is to steady the socket-stem in proper position, and prevent leakage of gas between the base and stem. v

It is evident that, when desirable, permanent, instead ot' movable, lavaV tips may be secured Within the socket-stem. In constructing this burner, the threaded socket-stem should be made to operate into the base with as much friction as practicable, to prevent leakage ot' gas during the regulation ot' the-llame.

After having described my invention, what I claim as new, 'and desire to secure by Letters Patent, is-

As an improvement upon the old Scotchtip burner, and, in combination with the base A, the threaded socket-stem B, with closed lower end e, perforations cc, and check-nut d, as herein the whole being arranged to Operate 4set forth.
